I don't really mind the rule, but it was more boggling last tour where they had a photo contest where they encouraged photos and to share them on Facebook. Then you get to the venue and I get yelled at for taking a pic and they said it was the band's request.
Then why have a photo contest if I can't take a picture?
Well, again, the band's rule is NOT "no pictures at all." The band's rule is: "no pictures during performance only," and they otherwise encourage pictures. Some security teams at some venues are misinterpreting and enforcing it differently. But that has been the case in the past as well. I think it is just showing up as more of an issue this time around because they are playing a lot of different venues.
Think of it this way. The band talks to security managers at three different venues and it goes something like this:
Venue #1DT: Okay, so our policy is no pictures during the performance. Please have your guys enforce it strictly. But outside of the performance, we don't care if people take pictures, and we actually encourage it. Got it?
Security Manager: OKAY, GOT IT! THIS IS WHAT WE DO, MEN!
DT: Um...why are you yelling?
Security Manager: NO PICTURES WHATSOEVER. YOU SEE A CAMERA OR PHONE, YOU KILL THE MAN HOLDING IT, UNDERSTAND?
DT: No, wait...that's not--
Security Manager: VIPER 1 AND VIPER 2, YOU HAVE THE GUN TOWERS! VIPERS 3-8, FRONT OF HOUSE! VIPERS 9-12 ARE ROVING! REPORT TO THE ARMORY! MOVE, MOVE, MOVE!!!
DT: Okay...we're just gonna go do sound check now...
Venue #2DT: Okay, so our policy is no pictures during the performance. Please have your guys enforce it strictly. But outside of the performance, we don't care if people take pictures, and we actually encourage it. Got it?
Security Manager: *takes a long, deep toke and then exhales* I wonder if the snack bar has nachos out already...
Venue #3DT: Okay, so our policy is no pictures during the performance. Please have your guys enforce it strictly. But outside of the performance, we don't care if people take pictures, and we actually encourage it. Got it?
Security Manager: No pictures in the main auditorium during the show. Pictures elsewhere, fine. Got it.
